Commit d045019f0f use the variables
API_MAX_VERSION and DEFAULT_OS_COMPUTE_API_VERSION with wrong way.
API_MAX_VERSION means the max version of client supported. This
variable only be changed when client support the new version. And
it's must bumped sequentially.
DEFAULT_OS_COMPUTE_API_VERSION is default value of option
'--os-compute-api-version', this value decided the default behaviour
of nova client. The nova client CLI behaviour should be that client
negotiate with server side to find out most recent version betweeyn
client and server. So the value should be '2.latest'. And it won't
be changed except we decided to change the default behaviour of nova
client CLI.
